The best strength depends on the individual and the reason for treatment. The original content notes that treatment often starts at a lower dose and may be adjusted based on uric acid levels and tolerance.

Allopurinol is often used as a long-term treatment for ongoing uric acid control. The length of treatment depends on the condition being treated and the advice of the prescribing clinician.
